IMPROVEMENT IN QUILLS FOR SILK.

Specieation forming part of Letters Patent No. 117,612, dated August 1, 1871.

To all whom t may concern:

Be it known that I, IRA DIMOCK, of the city of Boston, in the county of Sul-folk and State of Massachusetts, have invented a new and useful Improvement in Silk-Quills; and I do hereby declare that the following is a full, clear, and exact description, reference being had to the accompanying drawing forming part of this specification, and in which- Y Figure 1 represents a longitudinal View of a quill with silk wound upon it and displayed and secured in accordance with myimprovement, and Figs. 2 and 3 are opposite end views ofthe same. Fig. 4 is a longitudinal View of a like quill with the outer end port-ion ofthe silk differently passed from end to end ofthe quill.

Similar letters of reference indicate corresponding parts.

My invention relates to the displaying and securing of silk or other thread on paper tubes, commonly called quills; and consists in a construction of the quills with slits across their opposite ends, whereby, v.after the silk has been wound upon the quill, the outer or loose end ofthe silk is passed crosswise through the slits at the one end of the quill, and then run or p passed 0n the outside of the wound portion of` the silk to the oppositeV end of the quill, where it is secured by passing the extreme portion of the loose end of the silk in a crosswise direction through the slits at such opposite end of the quill. Bythus arranging and securing the loose end of the silk not only is said loose end or portion firmly secured in a twofold manner at opposite ends of the quill, but the body or wound portion. of the silk is restrained at both ends from workin g oft' the quill, and a better display is made of the silk, whereby to judge of its grade or quality.

Referring, in the first instance,`to Figs. l, 2, and 3 of the drawing, A represents the quill, formed with slits a a' a-nd b b Yacross its opposite ends for a short distance only of its length. The

silk c is wound upon the quill in the ordinary way, and its outer or loose end portion c then passed crosswise through the slits a a at the one run in reverse diagonal directions from the slits a and b respectively, as represented in Fig. l; or the loose end portion c of the silk may be passed, as described, lirst through the slits at the one end of the quill, and then be wound once or more spirally around the closely-wound portion or body c, and afterward be passed through the slits at the opposite end of the quill, as represented in Fig. 4. In either case, or however the loose-end portion of the silk may loe run from end to end of the quill, it is important that the same should be secured in a twofold manner 'by passing it through the slits at both ends of the quill, and whereby the body or closely-wound portion c of the silk is restrained at both ends, as it is by the heads Vof a spool, from slipping or working oli' the quill. The exposure of the loose-end portion c ofthe silk in its passage from end to end of the quill on the body or closely-wound portion c facilitates the examination of the silk as to grade or quality.

What `is here claimed, and desired to be secured by Letters Patent, is-

The method herein described of putting up silk or other thread by winding it on a quill and then passing its loose Orouter end through slits in its opposite ends of and on opposite sides of and directly across the quill, and I longitudinally o'ver the latter, substantially as specified.

IRA DIMOGK.
